The bagging zone, that is.
This cashier is so conscientiously bagging the frozen items in the insulated bag that he is not even attempting to scan them. Is this on purpose or just an oversight? No matter the reason, the outcome is the same. The estimated loss to the retailer on this transaction is $50 (estimated by the retailer). Using ScanItAll, the retailer caught this transaction and will be able to mitigate future loss.
